Unlike most pop stars (Rihanna and Harry Styles, we're looking at you) actors have to be careful not to cover themselves with tattoos - obviously if you're playing an 18th century chambermaid or an alien life form from the planet Zog and you're head to toe inked up it's a little bit distracting.

So we're surprised Kristen Stewart has opted to go under the needle for the first time ever, and in what looks like a very visible place.

In photos from the Facebook page of Pride and Glory Tattoo Parlor in Nashville, the Twilight star poses with the tattoo shop staff and appears to show off a very small design on her wrist.

So tiny in fact, it reminds us a lot of that episode of Friends where Phoebe and Rachel get tattoos done and Phoebe comes back with a blue dot instead.

Maybe Kristen also had second thoughts when the scary big needle started buzzing?

Confusingly she's also pointing to her elbow.

We hope she didn't get tattooed there - it would look weird when you bend your arm and the skin goes all saggy there.

So what DID K-Stew get a tattoo of?

Our bet is on an anchor/swallow/heart or something else inoffensive.

Or maybe some really deep quotes because she's, like, so misunderstood.

We'd love it if she'd got 'Twilight sucks'.

She certainly looks chuffed with whatever design she went for (Image: www.facebook.com/prideandglorytattoos)
